APPARATUS FOR APPLYING GLOSURES T0 IPACKAGES.

of Illinois, have invented a 'certain new and useful Improvement in Apparatuses for Apl ing Closures to Packages, of which the o lowing is a specification.

My invention relates to an lapparatus for applying closures to packages 'and is illustrated diagraimnatically in one form in the accompanying drawings, wherein- Figure 1 is a plan view; Fig. 2, a section along the line -2-2 of Fig. 1; Fig. 3, a sec-4 tion alon `the line 3-3 of Fig. 2 .on a re- Like; `partsare indicated by likeletters throughout the several figures.

A is a table from which proj the housing A1.

A2 As are bearings mounted on the housing A1.

A'1 is a cap to`close the upl of the housing A1 and to comp ects upwardly er open end ete the bearings A2 A1".

A is ya shaft rotatably and slidably mounted in the bearings A2. A11.

lA is a sleeve slidable on the shaft A11 located within the housing A1, interposed between the bearings A2 A and splined to the shaft A5.

A7 is a driving sprocket rigidly mounted ou the sleeve A".

A8 is a collar rigidly mountedon the shaft A5 and adapted by its contact with the bearing A3 to limitrthe movement of the .shaft toward the rear of the machine.l

A 1s a compression spring surrounding the shaft A5 interposed between the washers A1 A11 which bear respectively against one end of the bearing A1 and the collar A12 on the end of the shaft A. The spring A9 has for its function to yieldingly hold the shaft in its rearinost position with collar AB against the bearing A11.

B is a supporting frame for the table A.

B1 B1 are brackets downwardly depending from 'the table A, and carrying the shaft BB.

B1 BS are nuts and washers respectively mounted on the shaft i33 and engaging the bracket B2 to hold the shaft in osition. The bracket is cored out larger t an the conveniently centered.

Bo is a clutch disk rotatably mounted on the shaft B11 having a single slot E'1 in its periphery. 'B8 is the conical clutch surface of said disk., I

` B9 is a sgr-pocket rigidly attached to the clutch disk B1o is a sprocket chain connecting the sprockets A1 and B. The two sprockets A1 and B 4are so proportioned that for every single revolution of the sprocket B the sprocket A7 makes three revolutions.

B11 is a collar rigidly attached to the shaft B by the set screwrB12.

B1 is a ball thiustbearin the shaft B1. and interpose between the collar B1l and the hub B1* on which are ly mountsurface BB in the clutch member or disk 13.

C1 is a collar rigidly attached to the sleeve C.

C"I is a ball thrust bearing rotatable on the sleeve C.

CG is a compression spring surrounding the sleeve C interposed between the thrust bearingC and the pulley C1. C1 is a grease cup communicating by means of the passa e C1 anddscharges C8 C1 with the outside of the shaft B3 to lubricate the bearing surface between the shaft and the sleeve C and hub B1.

I) is an actuating levc'r pivoted on the bracket B1 and havlng a forked clutch operating finger D1 'straddling the sleeve C the bearing C1'.

and adapted to ride upon the 'cylindrical surface of the disk B'1 and to engage in the slot B1.

D is a tension spring interposed between the controlling member D and the bracket against the isk B and to cause it to enter the slot B1 when they are `in opposition thus rotating the forked portion D1 to Withdraw the clutch. y

D is a counterhalance weight to yieldy 5 ingly hold the latch Dt in upright position.

D an. adjusting] screw to limit the rotation of the latch il* in the member D.

D7 is a conical cani member rigidly mounted on the shaft A5 in opposition to the latch D* and adapted to be moved forwardly to engage the latch and press it vagainst the screw D and rotate the member D: to engage the clutch and lift the roller D2 out of the slot `and permit it to ride on the disk B".

D8 is a guard disk located on the shaft A in front of the cam member D".

E E1 are spring fingers projecting `:forwardly from the shaft or spindle A5 and held apart by the stud E2 and held together by the screw E3.v E41 EE are hooks projecting outwardly f. from the ends of the lingers E E1 to engage wiEre bag tie' E about the neck'of the a 7. gels EB are bag tie ringsl whichv are carried on ythe ngers E El adjacent the guard D3 until needed. lF is a' bracket projecting upwardly from thetable A carryingslidaoly and adjustably mounted therein the two parallel spring rods'l?"1 F2.

Fs 1s a cap bolted to the bracket F to hold the rods F1 F2 in position.

F4 F5 are outwardly bent portions of the .lingers F1 F2 to permit the easy insertion of the bag.

The use and operation of my invention are as follows With the driving pulley driven from anysuitable source of power by a belt as above indicated the operator takes his place before the machine and inserts the neck of a bag between-the two spring-crimping fingers. He then, holding Avone hand at the outer endof the spring crimping fingers,

brings the bag forward with the other, catching it in his hand as lit leaves ing fingers. The result of this is to crimp the neck of the bag as indicatedA-in Fig. l. He then takes one ofthe bag 'tie riiigs on the twistingiingers, pulls it forward, drops it over the'neck ofthe bagand catches-it in the hook. He then, holding the bag firmly with his two handsone above and the other the machine. v This straightens` tie somewhat as indicated in Fig. compressinglgv the tension spring and causes/ theconica Acmninember to come in contact. with the o0 latch, bearit down and rotatejthe" actuating lever. This rotation of the actuatinglever.

throws theA `clutch into the operating posi1- tion and permits. thev driven member to rotate because ythe roller' which normally, ocA e5 cupies 'the slot therein has meanwhile been' the crimpf below the bag tie, pulls forward away fromv out thebag.

withdrawn. The roller then rotates; onV the outer periphery of the disk vwhilethe disk makes a single'revolution. This single revolution of the clutch disk causes the twisting. spindle to make three revolutions and twist thbag tie firmly about the bag. The cam roller drops lbac into the slot `at the end of the 'revolution and the clutch is disenfgaged. The operator then can withdraw the bag. 75

The clutch it will be notedis compressed -into the' operating position by a spring. The function oi'` this spring is to provideffr irregularities or inequalities in size, shape or arrangement of parts so that there 1s no possibility obinding and so that they need not be made with any great degree of ac-l curacy.

'It will be noted that in Fig. l the twol one from the other andthe operator in order yto permit the'twist at all must,` when he. draws back on thebag to throw the clutch, bring his thumb and one linger around the neck of the bag and press the ha tie together thus locating the point at 'w ich the twist starts. By this movement he of course locates it `adjacent `the bag andv the twist will then pro ess away from the bag. Thus there is no' anger of the bag being 95 too tightly constricted and there is no dan- `ger of any breakage of the bag tie itself such as so frequently occurs when the twist works both ways.
